Be it known that I, WALTER W. HUN- ziounn, a citizen ofthe United Statesof Anierica,residing at Mansfield, inthe county of RichlandV and Stateof Ohio, have invented certain new and useful Improvements in ReelingDevices, of which the following is a specification. f.

This invention relates to improvements in. reeling devices and has moreparticular refcrence to the reeling and resetting mechanism. It isparticularly adapted to usein` controlling trolley poles and in myspecifica#` tions I have so described its application and operationalthough my invention has other ap lications. i

ne object of my invention is to `provide ari-improved device of thischaracter which will be simple, durable, reliable and comj` pactinconstruction, and effective and efiicient inoperation. i

LXnother Objectis to` provide trolley re` triever embodyingmechanismcontrolled by the `tension of the retrieving spring forautomatically setting the locking means when restoring the device tonormal operating condition. A further object is to provide a device ofthis character comprising means whereby it may be adjusted` "to j obtainany desired amount Vof retrievingr action. i

Other objects of the invention more fully hereinafter.- j

The invention consists substantiallyin the construction, combination,location and` errangement of parts, all of which will bemore fullyhereinafter set` forth, and claimed, and illustrated in the accompanyingdrawings, in which: i j j Figure l is a side view of a reeling deviceembodying my improvements and `shown partly in section to illustrate theconstructional arrangement of the various parts. Fig. 2 `is a sectionalview taken on the line 2&2 of Fig. 1, and showing the parts in normaloperative condition. j

Fig. 5` is a view of a portion siteside ofthe retriever disk. Figs. 6, 7`and 8 are views showing the lookin-g mechanism and the operating means1n various positions and which will be re# :ferred` to hereinafter.

The same reference characters indicate the sameparts throughout thevarious views.`

Referringto the drawings and which illustrate the embodiment of the`preferred form of my invention, I provide a `casing 1 provided with acover 2, `which `maybe removof `the oppo;

ablyfsecured thereto in anv well knownor suitable manner. The casingisformed with a recess wherein is mounted a power `or retracting spring 8,whichhas its outer` end connectedto the stud 4,of an actuated member',provided with a pin 6, to be referred to hereinafter. The `.upper endoft-his m`e`mber 5f is `slidably mounted between `lugs 17, i formed onthe casing, whileqits lower or rcduced end 8 extends within a cavity 9formed in a projection provided on the` casing.` Mounted Within thiscavity is a compression spring 10, one end of which bears against thecasing at 11,1while itsother end operates against one sideof a nut l2having threaded engagement with the member Whenthe device in operativecondition the member` 5 is held in' the position shown in Fig. 2, thetension on the spring l() being balanced by the tension of the powerspring-fi when it is wound up.` In this positionof `the member 5j, itwill be noted that its shoulder 13` is held inspaced relation to theshoulder 14 of either direction uponthe shaft 17.

"lock the retriever disk to the casingso as to..

Ypreventits rotation and to lhold the power spring under tension.`Thislatch comprises Cli two levers and 21, which are pivoted at 22-andf23 respectively. lTheir inner or adj acentlends are pivotallyconnected together so that they will both be moved simultaneously. rlhelever 20is notched at this end while the correspondingend of the lever21 is formed and adapted to operate in said notch so that the two leverswhich constitute the latch form substantially a lfnuckle jointed device,as shown in Figs. 3 and Il. lVhen thelatch is in locking position, thefreeends 24 and 25 respectively'will be projected or thrownoutward'beyond the iiange on theretriever fdisk and in positionV toengage the fixed lugs 26 and 27which are 'formed integrally on the'innerwall of the casing. For

convenience of description l will hereinafter refer to the end 24 of thelatch as the lock7 end, and the end 25vas the stop end. rhus x it willbeseen that when the latch is thrown lwhen said levers are in released.4position, asV

out andthe lock7V end 2li engages the. stop lug 26 the retriever `diskwill be positively lockedl yagainst rotation in a direction to wind upthe trolley rope. The operation ot the stopend of the latch willbedescribed hereinafter. The two levers 20' and 21 which comprise thislatch, are 'curved to coincide with the curvature of the ange 18,V sothat shown'in Figs. Gand '7, no portion of thein will project beyond theperiphery of the re' triever disk, thus leaving the disk free torotate.For the purpose of maintaining the latch in either position I provide aspring 28, (see Fig. -5). This spring has its inner end'secured to thedisk at 29 while its outer vend is connected to the free end of one ofthe levers as shown, vthe relation of the parts being such that when thelatch is actuated it will be moved completely to one or the other of itstwo positions, as the case may be, and held there bythe spring-28. Y Y

Rotatably mounted, preferably upon another hub extension 30 of theretriever disk,

'- is a' drum S1 adapted to receive the trolley rope 32.V This drum isAformed with a compartnfientr wherein is mounted a service spring 34,which operates to rotate the drum in the direction tokeep the trolleyrope taut. The outer endet this spring is'connected to the drumrin any'suitable'or desirable inanner while its inner end kis connected to aratchet sleeve 35, which is mounted for :uljustment by means ot ratchetteeth between the sleeve and thc liked shaft 17.

The drinn, being connected to the rope cured. to the trolley pole,normally follows the movement oli' the trolley pole and in ease oi? an'abnormally rapid rise in said pole, mechanism is actuated which willunlock the retriever disk and connect it to the drinn so lthat the drumwill be rot-ated in the direi-,-

tained in inward or retracted position bv .15

springs 39, the free ends of: the dogs resting against the adjacentbosses as shown in Vig. l. These dogs are arranged so that they will hesensitive to abnormally .rapid llurlnat ionsy of the trolley pole, suchior instaure as when the pole leaves the wiie and .dies upwardly.Because ot the undue speed ot the drum iiicident to the quick upwardmovement of the pole the dogs will move outwardly against the peripheralflange 1S on the retrnver disk under the action of centrifugal vtorce.

will be noticed that the knuckle oint ol' the latch, when the latch isin locking position, lies within the flange 18 and hence within the pathof the tree ends of the tripping or centrifugal dogs 36. In consequence.the tripping dog, which at the instant is the, nearest to the knuckleoint of the latch, will strike said joint and force it outwardly, thusthrowing the lock and stop ends of the latch inwardly and release theretriever disk. ln order to insure a positive releasing action on thepart of the dogs, I provide an outstanding rib L10 on the face of theretriever' disk adjacent the centrifugal dogs. This rih is positionedadjacent the knuckle joint of the latch to provide a comparativelynarrow space between the rib and the flange 1S. ln addition the freeends of the tri piling dogs are provided with extensions 4:1 ofsullicioiit thickness to pass through the channel or space between therib and liange and therehv positively -force the knuckleijoint olfV thelatch outwardly. Assuming now that the latch 20 has been disengaged fromthe stop 26 and the retriever disk thus released. it now remains to lockthe retriever disk and druin together so that the retriever disk willrotate the drum in the direction to wind up the trolley rope and pulldown the pole. rlhis is accomplished by the centrifuge tripping dog 36which, after actuating` the knuckle-joint, passes said latch andcontinues until it reaches the shoulder e2 formed in the flange 18 ofthe retriever disk.

thus engaging said shoulder the tripping dog positively interlocks theretriever disk and drum and the latter willthereby be car ried with theretriever `disk vand willfwind up the trolley rope.

i is in released position, `to assume aposition in proximity to the endoi the rib as` shown in Figs. `6 and .7, and the purpose ot which willbe described hereinafter.

In order that a clear understanding of my invention maybe had, abriefvstatementt of` the opera-tion is as follows. When the powerspring-is .wound up or set and the parts are in their normalposition`they will be Vas rep resented in Figs. 1,2,` 3 and 5. The latch will bein outward position and the lock end 24 oi' the leverQOheld inengagement `with the lock lug 26 of the casing. The member 5 will .beheld in the balanced position shown in Fig. 2 in which the compressionci the spring 10 is balanced by the tension oi the power spring 3. Inthis position of the member 57 its pin 6 is disposed below the end 45 ofthe guide rib 4321s shown in Fig. The centrifugal dogs 36 will be heldin engagement with the bosses 38 and the drum will be under the actionof the service spring and 'tree to rotate in either direc tion and thetrolley rope may be wound or unwound thereon. When the rope is rapidlyunwound from theidrum as when the trolley pole lumps the wire, thesudden impulse or rapid rotation of the drum will cause Athe dogs 35 to`moveoutwardly by centrifugal torce and actuate .the latch and releasethe retrieving disk and finally interlock the drum with the dish in themanner described. (See Fig. 4.) When this has taken place the parts willbe in the position shown in Fig. 4. After the latchQO-Zl has beentripped by the centrifugal dog 36 the end 44` of latch 2() will assumethe position shown i in Fig. 6 with respect to the/rib 43.. Next theretriever dial( and the drum `will be caused to rotate in the ropewinding direction and wind up the rope `by the action ot the powerspring 3; thereby pulling down the vtrolley pole. AS the drum rotatesina rope-winding or countcir-cliicliivise direction, the power spring,which .normally holds `the actuating member 5 in extended position,weakens whereupon the compressionspring l() willimpart movement to themember 5in thedirection to cause its shoulder 13 to engage theshoulderi4 or the case. In this position of the member 5, its piir will bepositioned as shown in solid lines, Fig. and in which. position it iscompletely out of the path of the guide rib 43. VAssuming now that thetrolley rope has been wound up and the trolley pole pulleddown, it nowremains to reset the de vice to normal operativecondition. In order toaccomplishthis `it is only necessary to pull out onthe trolley rope,thereby unwinding the rope from the drum and turning `the drum and theretriever disk in the direction indicated by arrow in Figs. G, 7 and S.As the rope is pulled out and the drum and retriever disk revolves, thepower spring will be wound up until its tension becomes equal to orbalances `the pressure exerted upon the actuating member 5 by thecompression spring 10. Then upon continued rotation of the partsinthesame direction and the consequent further tensioning ot' the powerspring the member by reason of its connection with said spring, will be`caused to moveagainstthe action of the spring 10, until` its pin ('willbe lin `the positionindicated by brokenlines1 Fig. 6.` It will beapparent that when `the member 5 is in this position by continuedrotation' of the disk` n'iovement will be imparted` to the member 5byreason oi its pin 6 riding over the guide rib 43 and that theextension 44 oi the lever y 20 will be brought iuto engagement with thei pin 6 and forced to move outwardly (see Figs. 7 and 8) and thus throwthe latch into` locking position. The guide rib 43 has an upward pitch;that is, its approach or 4toi Y the rib. Theoperator continues pullingout on the rope until the stop end 25 (F ig. S) of the latch strikes thestop lug27 on the casing whereby further winding up of the spring orunwinding ot' the ropeV will be positively prevented and in whichcondition or relation of theparts thepin 6 will. be out of engagel mentwith the guide rib 43 as in Fig. As

soon, then".` as the pullon the trolley rope relaxed the disk will movein the reverse direction `until the lock end 240i' the latch `is broughtinto engagement with the loch stop 2610i the casing and locks the diskagainst triug-al dogs. the parts when the device is in normal operativeconditiom l From the foregoing it will be apparent that the mechanism`which operates to automatlcally restore the latch tnloclring pos1` tionis governed by the tension of the comy rotationuntil itis againrcleasedby the cen Figa lshowa therelation ot pression spring 105 and that by`varying the tension of this s pring,. theldevice may be ad]usted toobtain any desired amount ot retrieving action within its limits otoperation.

Ylt now remains to:l release thev drum from the retriever disk, -Whichhas been held interloclred vWhile the-'aparts -were being restoredtonormal operative'condition. This isaccomplished as soon'lras ,the pullon the trolley-rope is'relaned whereupon the drum Wiil start torota'tein the opposite direction under theiniiuence ot-the servicespring 84,

A and in this movement it lcarries the .centrifugal dog out oiengagement Wlth the stop shoulder 42 Lof the disk. VThis dog moves ontuntil it. passes' theVV end of the ridge 46 and-it is then drawninwardly against the y 7 boss 38 by its spring 39thus iinally unlock-'l5 ing the drain from the 'disk and leaving the drum tree. toagain'normally Wind up and Y y.unwind the trolley rope.
